input: i8042: Provide feature to disable keyboard before booting kernel
The BIOS leaves the keyboard enabled during boot time so that any
keystroke would interfere kernel driver initialization.
Add a way to disable the keyboard to make sure no scancode will be
generated during the boot time. Note that the keyboard will be
re-enabled again after the kernel driver is up.
This code can be called from the board functions.
